Abstract
A thermal management system includes a thermal management circuit through which a thermal medium flows and an electronic control unit. A first water pump is provided upstream of a second water pump in the direction of flow of the thermal medium with a reservoir tank as a start point when the thermal management circuit is in a series connection state in which the reservoir tank, the first water pump, and the second water pump are connected in series with each other. The electronic control unit drives the first water pump earlier than the second water pump on condition that the thermal management circuit is in the series connection state when the thermal medium is injected into the reservoir tank.
